Specification of Letters Patent.

Original application filed January 20, 1909, Serial No. 473,245. Dividedand this application filed March To all whom it may concern Be it knownthat I, HARRY LUKE Owns, a citizen of the United States, residing inSchenectady, county of Schenectady, New York, have invented ImprovedMeans for Applying Coverings to l/Vires, of which the following is aspecification.

This invention relates to a means for facilitating the application ofasbestos fibers to wires in forming insulated electric con ductors.

According to my invention I am able to receive the asbestosfiberdirectly from the carding machine upon a suitable temporary backingof conveying material, upon which it is deposited in the same state asdelivered by the dotfer rolls thus retaining its flocculent condition.Thistemporary backing is a flexible, ribbon-like sheet, which with thedeposited flocculent asbestos is; wound up into a coil on a reel orbobbin, so that it may be stored for future use or inserted directlyinto the wire-covering machine for application of the asbestos upon thewire.

In the accompanying drawing, Figure 1 is a partial sectional elevationof the delivery end of a carding machine showing the method of preparingthe coil of asbestos fiber on its backing; Fig. 2, is a section of thereel and coil on alarger scale; Fig. 3, is a plan view of a part of themachine shown in Fig. 1; and Fig. 4, is a side view of the roll ofasbestos on its ribbon-like backing when removed from the bobbin.

In Fig. the main carding drum is iridicated by 1, while one of the setof dotfer wheels is indicated at 3. In the rear of the set of dofferwheels 3, I place an eccentric or cam shaft 4, to impart a verticallyreciprocating motion to the combs 5, which are can ried by a shaft- 15,one comb being supplied to cooperate with each of the (lotfer wheels 3.On a lower plane and adjacent to said combs 5 is rotatably mounted anidler roll (3, over which the tapes 20 of any suitable material, aredrawn, while below said roll 0 is. mounted another idler roller 7, uponwhich rests the flanges of therunwinding rccls. Each of these reels ismade up of a hollow hub or spindle 3 and the. removable flanges 9 whichare held in place on the reduced ends by the. circular nuts 10,scrcwthreaded upon the ends of said spindle b7 and formed each with agroove it in its periph- Serial No. 616,814.

erv. place lengthwiseof the supporting shaft by the friction springs 12which are secured to the cross-bari3 and have their free ends engagingthe grooves 11 of the reelspiiidle.

The reels are detachably detained in Th'usthe. reels are permitted to berotated as the tape is unwound therefrom. The springs 12 are placed inpositions each to' retain a tape reel' opposite a dofferwheel. At therear of the combs I provide another set of tape reels of similarconstruction and interchangeable with those of the first set, but thesereels of the second set are for.

winding up. Under this second or winding up set of reels'is mounted thedriven shaft 1 T, upon which are keyed or otherwise se- Said windsecured in placeion its supporting spin le by the springs 12 will:haveits outer end brought up over the roller 6 and thence to the windingreel driven by the shaft 14 so that said tape will be wound up onsaidwinding reel' by the action of the friction disk 15. The directionsof movements of the several moving parts are indicated by the arrows inFig. 1. As the tape 20 is thus transferred from one reel to the other,the

combs are reciprocated by the revolution of the shaft 4 and the asbestosfiber is thereby combed-from the dotfer wheel 3 down upon thetravelingtape 20, which is being wound with the-depositedo asbestos upon" itselfon the winding up reel. The'asbestos fiber is retained and protected bythe successive coils of said tape 20 whichserve as a temporary backingtherefor. When the reel filled it can be readily removed from, themachine and transferred tofa suitable wire covering machine forapplication of the asbestos fiber to the wire. \Vhcn emptied of thefiber and its ribbonlike support the reel can be returned to the cardingmachine to be refilled.

From the foregoing description it will be I soon that any suitable widthof tape may be emplovcd and that the asbestos fiber will bedepositedthereon' in'a. perfectly even state and the thickness of thedeposit upon the tape may be regulatedby the speed at which 1 '-tlietape is made to travel.

I do not in this application intend to claim either themechanism for orthe method of preparing the roll of the ribbonlike support carrying theasbestos as they form the subject of my application for pat- 7 cut filedJanuary 20, 1909, Serial No. 473245 a web of flocculent asbestos fiberdetachahly supported thereon.

2. As a new article of manufacture, a flexible sheet or ribbon-likesupport, having a Web of flocculent asbestos fiber dctachably supportedthereon, the ribbon and web being rolled up into a ball or reel.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
